Fatal Error?

[Fernan100tifiko 3]

I'm doing a translation of the game into Spanish, however, when I want to try it to see how it goes, this message comes out.

Until a few days ago the error was "repairable", the message still came out, but after a few days the game returned to normal, I even saw all the translation that I had been doing until then.

For days I have wanted to try the game again, but it is no longer working, it does not enter and I fear that it has been for the translation, or even worse, that all the work of weeks has been in vain.

If anyone has previous knowledge about these programs, or about what is happening, I would greatly appreciate a solution.

It's not like I'm desperate, but I would feel really bad if everything I've done has been for nothing.
